RU kidding? It's a piece of cake. I've never had a problem, including airport security with Xray scans. Just buy a large bottle of pills that come in capsules (some kind of powdered vitamins, preferably close to same colour, etc.) take one apart, remove as much powder as you're going to add, mix in the contents and re-cap. Don't forget to discretely scratch the side of the capsule you added to or you'll need to take them all, lol! I've never even had a container opened in security......but then again, I'm old (and probably look like I need the vitamins)! I also am not trying to advocate others taking risks - it's entirely up to you.
